From Pathfinder Wiki

A bridge composed of connected elements (typically straight) which may be stressed from tension, compression, or sometimes both in response to dynamic loads. Truss bridges are one of the oldest types of modern bridges. The basic types of truss bridges have simple designs which could be easily analyzed by 19th and early 20th century engineers. A truss bridge is economical to construct owing to its efficient use of materials.
